One the measurements provided by regionprops is 'Centroid'. Here's an example of labeling binary objects, computing the centroid of each object, and plotting the centroid location on top... 더 읽어보기 >>

Earlier in this series I have discussed the problem of plateaus. Specifically, how do you assign a flow direction to a DEM pixel that has no downhill neighbors? I proposed in part 5 that the... 더 읽어보기 >>

The functions bwlabel and regionprops are very useful for measuring the properties of shapes in a binary image. There are documentation examples and product demos showing how to do this,... 더 읽어보기 >>

About twelve years ago, I was implementing the algorithm that became roifill in the Image Processing Toolbox. In this algorithm, a specified set of pixels is replaced (or filled in) such that... 더 읽어보기 >>

After my last upslope area post, I decided that I had enough of the algorithm details worked out to produce a set of working M-files. Although I have a few more posts to go, I've already uploaded... 더 읽어보기 >>
